VJ 24 SunFun, Basic Canadian ultralight aircraft, by Volmer Jensen, Ultalight Aircraft Canada.

ltralight Aircraft Magazine - VJ 24 - Volmer Jensen VJ 24 SunFun -  Tim Lohrey gives us a quick look at the Vj 24 SunFun, ultralight aircraft from Volmer Jensen Aircraft during the E.A.A. Airventure Convention held at Wittman Airfield in Oshkosh Wisconsin. The Volmer VJ-24W SunFun is a high-wing, strut-braced, single-seat, ultralight aircraft that was designed by Volmer Jensen and provided as plans for amateurbuilt construction from Volmer Aircraft of Glendale, California.

The SunFun started as a foot-launched glider design, the VJ-24, and was developed into a wheeled undercarriage motor glider, the VJ-24W. The VJ-24 was derived from the earlier Volmer VJ-23 Swingwing and differed from that design by replacing the wooden structure with metal and employing a constant chord, strut-braced wing in place of the VJ-23's cantilever, tapered wing.

The aircraft is built from aluminium tubing covered with aircraft fabric. The 36.5 ft (11.1 m) span wing is braced by V-struts, supported by triangular jury struts. The fuselage is built around a keel tube that mounts the cruciform tail at the aft end, the wing and cockpit in the center and the engine at the front. 
The specified engine is a Yamaha 15 HP, 100 CC go cart engine mounted in a tractor configuration on the front of the keel tube, on the aircraft's nose. The landing gear is of conventional configuration, using spoked bicycle wheels for the main gear. 

Pilot weight is limited to 180 lb. The take-off and landing distances with the 15 hp (11 kW) engine are both 100 ft (30 m). In 1998 plans cost US $100 and the estimated cost of the materials to build the VJ-24W were US $2400. The estimated construction time is 250 hours.

Ultralight Aircraft Magazine - Welcome to the Ultralight Aircraft News our goal is to cover as many aircraft expositions that host aircraft described as ultralight aircraft, light sport aircraft, experimental light sport aircraft, amateur built aircraft, ELSA or homebuilt aircraft that fit into the definition of ultralight aircraft in Canada or light sport aircraft, or experimental amateurbuilt light sport aircraft in the United States. 

These include three axis control aircraft, weight shift control aircraft, more commonly known as trikes, powered parachutes, helicopters, gyrocopters and powered para-gliders that meet the light sport or ultralight aircraft definition.

Airshows and aircraft expositions that we cover include, the Deland Sport Aviation Showcase, U.S. Sport Aviation Expo, Deland Sport Aviation Showcase, E.A.A.'s Sun N Fun, E.A.A.'s Airventure, the Midwest LSA Show, Copperstate, UPAC Convention and Aero Friedrichshafen in Germany. We try to regularly attend regional shows like the Arlington Fly-In, and Rocky Mountain Fly-In.
